MOLDERS FLASK.

SPECIFICATION forming part of Letters Patent No. 421,693, dated February 18, 1890.

Application filed October 9, 1889- Serial No. 326,458. (No model.) A

To a/ZZ whom t may concern:

Be it known thatl I, WILLIAM N. GARTSIDE, of Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Molders Flasks; and I do hereby declare the following to be a full, clear, and exacty description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

It 1s perhaps proper for me to here state that iiasks have heretoforebeen made in which the cope or drag or both were made in'two sections hinged together at one corner and unlted by a snap or catch at the diagonallyopposite corner, the object being to provide a iiask which could be easily manipulated and be capable of a more universal application; but the development of the iiask-making industry has demonstrated the desirability of providing a flask which may be shipped 1n small compass, and, when desired for use, set up with little or no labor and by an unskilled person.

It has been the primary object of my present efforts to produce a flask having these desirable qualities, and, further, to provide in connection therewith novel snap or catch mechanisms and steady-pin sockets, all of which when combined Will make one of the most perfect and reliable flasks capable of being produced. v

The invention therefore consists, broadly stated, in a flask formed in sections so united as to foldinto small compass, and, further, in certain novel details of construction and combinations and arrangements of parts, to be hereinafter described, and pointed out particularl y in the claims at the end of this speciiication.

In the accompanying drawings, Figure lis a perspective view of a iiask, constructed in accordance with my invention, having a single cope. Fig. 2 is a similar view of the same folded for transportation or storage. Fig. 3 is a detail perspective View of the preferred form of catch Fig. 4 represents a bottom plan and a side elevation of the two parts of the catch. Fig. 5 is a longitudinal section and elevation of the same. Fig. 6 is an enlarged View of the steady-pin socket and ange. Fig. 7 is a detail of one of thejoints.

Similar letters of reference indicate the same part-s in all-theV gures.

A A denote the sides of the flask, and B B the ends, said parts being united at the corners by loose connections, which permit of their being folded down flat on each other, as illustrated, for instance, in Fig. 2.

It is obvious that many different styles of hinge or loose connections may be employed at the corners, the only essential being that they should form a rigid strong structure when the flaskis set up; but the preferred and most convenient form for the corners C consists of angle corner-irons D, secured on the edges of the adjacent parts and preferably united ,rigidly to one of the parts 'and pivotally to the other part, the end of which latter abuts against the former, as shown in dotted lines, Fig. l, thus, when the parts are extended at right angles, forming a rigidj oint. A set-screw F is provided for holding the parts in' the position mentioned, which setscrew or a joint-bolt may be inserted through the holes d in the angle-iron D, but is preferably inserted through the end of the overlapping piece, as shown, thus providing an opening into which the screw maybe screwed when the parts are folded.

The hinge-joint at the corner E, Fig. 7, consists of pieces @,secured at each corner of the side and end, respectively, with projecting lugs e', united by rivets, and having the corners c2, which arrest the movement of the parts when they are brought into` line.

On the ends of the parts forming-the corner E are secured the sections of the spring snapV or catch, in the preferred form illustrated in Figs. 3, 4, and 5, consisting on one side of the plate G, having the extended end g, pointed and provided with the incline or beveled surface g and catch g2, and on the other side of the spring-latch h and its guide as follows: The base H, which is secured to the side of the flask, is provided witha recess I-I at the rear end, into which fits the T- shaped projectionv 7L on the latch h, and the upwardly-extending projection H2, against which the rear straight end of the latch abuts IOO when retracted, causing it to always assume somewhat and constitutes the point of theA latch with which the catch engages.

The T-shaped projection passes into the base through a transverse aperture 1,(seeV dotted lines, Fig. 3,) and is permitted a limited movement in the longitudinal aperture Z, thc forward movement being limited by the block m, inserted inthe recess in the base after the latch is in place. A spring L bears against the block m and tends to keep the latch retracted, and by forcing the straight portion against the projection H2 keeps it in proper position to engage the catch.

Then the parts are brought together, the latch is forced straight out by the cam-surface until it drops into the catch, and to release it it is only4 necessary to move the latch sidewise in either direction, enabling the latches on the cope and drag to be released simultaneously without the necessitv of providing different styles of catches tor each.

At each end of the drag are secured the` steady-pins N, triangular in cross-section,

and at corresponding points on the cope are secured the sockets O, into which they are adapted to fit in the well-understood manner. Each of the sockets is provided at the bottom with an extended flange O', having an aperture therein corresponding in shape to the 1 pin, and serves the double purpose of a guide and handle.

Above the iiange' are two pro- A.

jections l), extending outward from the base and substantially parallel with the walls of the opening in the iiange, which projections are connected at the outer end by the screw lVhen now, for any reason, it becomes desirable to take np wear in the socket, orl

to tighten the same on the pins, it maybe readily accomplished by tightening the screw Q. and drawing the projections together.

lt is obvious that other styles of spring snaps or catches maybe employed-snch, for instance, as illustrated in Figs. l and 2, in which simple spring-pressed latches R, en gaging catches S, are employed, the springs, for convenience, being located within the latches, and a socket provided for the catches to prevent twisting or side strain on the flask.

Several sections of cope may be employed, if desired, with suitable steady-pins and sockets arranged on adjacent sections, and the various details of construction of the parts may be changed or modified by those skilled in the art without departing from the spirit of my invention.

From the above it will be seen that I have produced a :fiask adaptable to any of the uses to which flasks are now put, and which combines the rigidity of the ordinary solid rectangular flask with the advantages of the separable fiask without the disadvantages and unreliability of the latter, at the same time being adapted to fold into small compass for shipment or storage.

Having thus described my in rention, what I claim as new isl.
